Monitoring of QoS in MANET Based Real Time Applications

Specialty of Mobile Adhoc Networks (MANET) is that in current mobile technology it is the most promising and highly developed elucidation due to its remarkable performance in offering network connectivity even in very radical situations of adversity where there is maximum chance of link failure and more necessity of quick set up of networks. The elemental routing procedure in a MANET involves facilitating unremitting communication in the network system between two mobile stations during required period of time and the basic factor being selection of the most suitable forwarding node to proceed the real time packets from source towards destination in such a way that the optimization of the network can be achieved by maximum utilization of available resources. Considering that real time applications are one of the most challenging issue in MANET, due to transportation of high volume of data including audio, video, images, animation and graphics, this paper presents a monitoring approach for checking the Quality of Service (QoS) conditions during competent routing using the concept of Mobile Agents. An intelligent mobile agent is designed in the proposed QoS platform that monitors and controls the QoS processing tasks using longest critical path method at the forwarding node to select it as the best option out of all neighbor nodes. Simulation results shows higher packet delivery ratio and comparatively reduced bandwidth consumption overhead when it is compared with other similar approaches.
